I have a three year old blind cat who is a complex character. He's a challenge right now and I really need some help. I am going to give as much info as I can in case anyone can see anything that I can't. He's not completely blind but whatever vision he has is limited. For the first 2 years of his life he was a very social cat. Lots of people in and out of the flat who he was friendly and confident with. He's very into routine and as long as I stuck broadly to that we were all good. This all changed about 10 months ago seemingly after I sent him to my aunts for a few days whilst I had a holiday (this wasn't his first time away from home). Since then he's been largely petrified of anybody new coming to the house and even skittish when it's people he knows or there's more than one person in the room. He has always been a bit of a pacer. I used to notice it if I was out for longer periods than the usual work day or hadn't played enough - fair enough he needed to burn off energy. A few months ago he started having violent seizures. He had one every 24 hours for a week until the vet finally agreed with my opinion that he was epileptic and prescribed medication. We are on low dose phenobarbital and have only had one break through seizure since. He doesn't love the medication but takes it without fuss. Recently I moved from a small flat to a 3 bed house which needs work - so lots of people coming and going to quote for jobs etc. He has been scared at times and cautious but given this huge change in his life not too bad. We have been here around 2 months. Over that time his pacing has reached the point of insanity, particularly in the evening after I come home from work. Sometimes he doesn't stop for hours - round and round in a large loop circle like a caged lion. Ive tried food, play, cuddles....anything I can think of to stop it or distract. Ive tried ignoring it because I read that that attention could act as a reward. I can't watch anymore. I am so worried that he's desperately unhappy or something is wrong and I don't know what to try. 3 hours of watching your animal do the same 2 meter loop is maddening. At times in the past when pacing was due to energy he would always want to play. Now he barges past as if i am not there like a zombie. Zyklene doesn't work. Feliway doesn't work. He's had a lot of recently blood tests due to the epilepsy and nothing wrong. I appreciate we've just moved, but things are getting worse not better. Does anyone have any insight over what could be wrong and what to do?!
